I added some tags to this image:
The tags I added were:
+5_toes +artist_name +biped +eyelashes +feet +hand_on_knee +hand_on_leg +legs_together +navel +nipples +pseudo_hair +scale_hair +scaled_tail +scales +toes
The tags already on the image were:
2020 anthro big_breasts breasts eyewear female glasses hi_res looking_at_viewer mammal monochrome nude pangolin shycryptid simple_background sitting solo thick_thighs wide_hips rating:q
When I submitted this change, it added invalid_tag as well.
So, I went to the Invalid: invalid tag wiki page and Ctrl+F'd all of the tags listed above, but none of them appeared on the page - either in the main list, or in the "The following tags are aliased to this tag:" list at the end.
(Incidentally, that wiki page also contains "See also: The current list", but that link just goes to a "not found" error page.)
This has recently happened on a few other images on which I've edited tags, too. For example, I uploaded these images a couple of weeks ago, and invalid_tag was added to the tags I put on them on the initial upload - I couldn't figure out what was causing it then, either:

1. What caused the addition of invalid_tag in this case of today's tag edits to that ShyCryptid pangolin image?
2. Is there a better way to figure out which tag caused invalid_tag than to visit that wiki page and Ctrl+F on each one in turn?
3. On the invalid_tag wiki page, should that "See also: The current list" link go to a working page?
4. The list on the invalid_tag wiki page was last manually edited in August 2020 - is it overdue an update?
5. Am I right in saying that the list "The following tags are aliased to this tag:" at the end of the wiki page is automatically generated, and contain all the tag aliases that lead to invalid_tag - but it doesn't list any tag implications that lead to invalid_tag?
